2-- The standard Mac OS X terminals Terminal.app and iTerm both declare themselves to be
3-- "xterm-color" by default. However the terminfo database for xterm-color included with OS X is
4-- incomplete.

6-- This terminal implementation modifies the standard terminfo terminal as required for complete OS
7-- X support.
